Sensor, method for same and engineering machine containing same

Abstract

The invention discloses a sensor, a method for the sensor and an engineering machine containing the sensor. The sensor comprises an acceleration detection device (10) used for detecting acceleration signals of an object to be detected, a signal conversion device (20) used for conducting primary integration and secondary integration on the acceleration signals to obtain speed signals and displacement signals and an output device (30) used for outputting one or more of the acceleration signals, the speed signals and the displacement signals. By means of the technical scheme, measurement of acceleration, speed and displacement can be achieved simultaneously in one sensor, assembly, disassembly and debugging of different sensors of different sensors in measurement of different signal quantities in the prior art are avoided, and measurement time is saved.

Description

technical field [0001] The present invention relates to the field of measurement, in particular to a sensor, a method for the sensor and a construction machine including the sensor. Background technique [0002] In the vibration test, especially in the vibration test of large structures, it is difficult to measure the velocity and displacement of the object to be tested. Generally, only the acceleration is measured, and then the acceleration is processed offline to obtain the velocity and displacement. But this cannot reflect the velocity and displacement of vibration in real time. [0003] If you need to measure the velocity or displacement, you need to replace the corresponding velocity or displacement sensor, rewire, and debug the acquisition program, which is very time-consuming and inconvenient in actual testing. Contents of the invention [0004] The object of the present invention is to provide a sensor integrating acceleration, speed and displacement measurement, ...
